To all 'whom t may concern:

Be it known that I, CHARLES JAMES, a citizen of the United States,residingst Youngstown, in the county of Mahoning and State of Ohio, haveinvented a certain new and useful Improvement in LocomotiveDriving-Boxes, of which the following is a full, clear, and exact descrition, reference being had to the accom anying drawings.

The general object ci) this invention 1s to provide a simple'andeiective locomotive drivin box so constructed and arranged that t e wornbearings may be replaced quickly and with little labor, and withoutrequiringl dropping of the wheels and the attendant disconnections.Another ob'ect is to insure the bearing members being rmly held in placewhile 1n use, though easily released for removal. Still another objectis to provide a simple and eiiicient thrust bearing carried on thedriver side of the box for receiving the lateral thrust of the wheel. yinvention is clearly illustrated in the drawin which show a preferredembodiment o it, and the essential and novel characteristics aresummarized in the claims.

In the drawings, Figure 1 is an inner end view of the driving box withthe cellar removed; Fi 2 is a plan of the box; Fi 3 is a vertice. crosssection in a plane para lei with the end of the box and looking awayfrom the driving whl; Fig. 4 is a vertical cross section through theaxis of the drivin axle; Fig. 5 is a llerspective of the arcua wedge forlookin t e bearing brass in place; Fig. 6 is an endg elevation of thebox from the driving wheel end; Fig. 7 is an elevation ofthe thrustbearing ring, removed.

In the drawings 10, 10 indicate two side walls of the box and 11 thearchshaped top thereof; 12 and 13-indicate vertical flanges them forlegs of the locomotive frame. at the top, as indicated nt 14, to rovideseats for the rin saddle. Below t e axle space is provi ed or the usualcellar.

In Fi 1( 3 and 6, I have indicated b the circ e A/the locomotive axle,which 1s journaled in the driving box. 20 indicates the bearing memberor brass mounted within the bo'x which engages this axle and supportsthe wei ht thereon.- This brass is crescent-shape in cross section,having a cylindrical interior concentric with the axle; and a slightlyconical exterior. The brass be made in one or more parte but ispreferablyA of three pieces of about equal arcual extent as shown in thedrawings. The frame of the box is recessedabove the axle and. at thesides, providing space in excess of that required for the brass. The boxalso has horizontal shinildcrs 16 on which the lower edge of the brassrests.

The outer surface of the brass 2Q stands a suitable distance within thecurved wall of the recess of the box, and into this recess is adapted tobe driven an arenal wedge 8l.

is wedge is shown as consistin ci" a portion of a cone, the innersurface owhich 1s concentric with the brass, the outer sur` face ofwhich is slightly tapered inward@- toward the driving wheel end. Thewall of the box recess is complementary to this outer surface of thewedge.

The wedge 30 has at its flange 31 provided with openings throu whichstuds may extend into the box. Suitable nuts 41 and 42.screwing ontothese. studs force the wedge tightly into place and thus force the brassown onto the horizontal inner end a radial shoulders 16 and effectivelyhold it in place.

A radial flange 23 extending outwardly at the outer end of the brassprevents its mov ing away from the driver, should it become loose.

I prefer to provide some clearance be tween the end of the wedge 30 andthe flange 23 and between the flange 3l and fthe 4adjacent face of thebox, so that the wedge may be effectively forced in by the nuts 41 untilthe brass is tightly clamped in lace. I prefer to provide notches 34 int e inner face of the wedge flange 31 to allow the introduction of aforce the wedge outwardly when the nuts are removed. Such outwardforcing of the wedge releases the brass and enables its convenientremoval.

In order to make the brass take the lateral thrust of the axle I preferto extend it downwardly beneath the horizontal diameter r of theraxle,'as shown clearly in Fig. 3, for

The wedge extends to approximately the same distance. Where the axle hasa reduced intermediate portion, a onepiece brass of more than half acircumference may be installed b lacing it over the intermediate partandI s iftin it endwise into place. If the axle is not thus reduced, thebrass is referably made in sections, as shown an this enables it to beplaced about the axle and slid into place in the box. It

example.

suitable pry to to take the wei ht o I wedge,

removing the y1'? prevents any is called a brass whether made in one ormore pieces. After it is in lace the wed e is slid endwise into place ansecured by t e nuts. I

To eil'ectively resist the thrust of the wheel against the end of thebox, I .provide a bearingring 50 which has a beveled outer edge 51extendingr behind an overhan 'ng arcual shoulder 1 on the box. To a lowthe convenient insertion of this ring I prefer to make the ovcrhanging a17 extend` only for the upper portion o the circumference and I maltethe ring 50.n parts, each of which is insertcd'from below with itsconcave edge upward and then given a artial rotation about the axis intoplace. l en in place, the sections of the ring are secured together, as,for example, by electric welding.

Figs. 6 and 7 indicate this thrust bearingring as made in two halveswelded on the lines 52 and 53. With this arrangement a half ring may bcinserted from below and rotated about the axis until it is above theaxle, then the other half of the ring may be lplaced below the axle andthe two rotated togetlieruntil their abuttinfv ends come into the s lacebelow the axle, where such ends may e conveniently welded together. Thenthe twopart rin may be given a half rota vtion to bringt eiotherabutting line beneath the axle, where these ends are welded together.Then the ring constitutes one complete whole. The overhangin flange dislacement of t e ring,

except possible The possibility of such travel may be prevented by a pindrivenV through the ring at any` suitable point..

he side frames 10 of the box carry an suitable cellar, in the usualmanner. Suc cellar is indicated at 60 in Fig. 6 and consists of abox-like member open above and adapted to be put in lace from below orfrom the inner end auf held b the ins 6l extending through ears 63 on te col. ar and throu h ears 18 at the lower ends of th`e box s des 10.

It will be seen that my driving box is very simple in construction, Toremove the brass it is only necessary te ack up the locomotive the axle'and remove 41 and pry out the arcual when 'the brass may be readily slidout .of place. The new brass may be rein stalled and locked in positionwith corra sponding ease, The thrust bearin ring may be readily put inplace, and, w en in place, will be ei'ectivev in recei' the thrust ofthe wheel, and, when'wolrn, the rin may be Vreadily `cut a artandiienjiovcd without Having thus described iuyinvention, what I claim1s: 4 y
